Description

Technical Field

[0001] The present invention relates to a platinum sensor, in particular to an automatic assembly device and an assembly method for a platinum sensor. Background Art

[0002] As Figure 24 shown, the platinum sensor mainly consists of a baffle 10.3, a sleeve 10.2, a fiberglass wire 10.4, a connector 10.1 and a temperature sensor. Among them, one end of the fiberglass wire 10.4 is connected to the connector 10.1 and the other end is connected to the temperature sensor, and the three are pre-processed into a temperature sensor assembly. The baffle 10.3 is sleeved outside the sleeve 10.2 and the two are welded into a whole. During assembly, the end of the temperature sensor component where the temperature sensor is located is inserted into the sleeve 10.2, and a part of the fiberglass wire 10.4 extends out of the sleeve 10.2. The sleeve is sealed on the side close to the temperature sensor to form a head 10.5, and the sleeve is flattened on the side far from the temperature sensor to form a flat head 10.6.

[0003] When the platinum sensor is applied to a high-temperature oven, the provided sleeve 10.2 (stainless steel tube, with a diameter of about 5 mm - 7 mm) can play a protective role, and other materials cannot withstand high temperatures. The baffle 10.3 is provided for the customer to install on the oven, and the screw passes through the hole on the baffle 10.3 for convenient fixation; the head 10.5 is provided to prevent external water vapor from entering the steel tube and affecting the product performance. The flat head 10.6 is provided to fix the fiberglass wire 10.4 inserted into the sleeve 10.2 to avoid loosening. In addition, after the temperature sensor is located in the sleeve, it must be ensured that it does not contact the sleeve 10.2 (stainless steel) to avoid short circuit.

[0004] During the processing, since the sleeve 10.2 is a stainless steel tube, heat sealing cannot be achieved, and it is easy to rebound and open when extruded and flattened at one time. The existing one-time flattening die is not very suitable for the stainless steel tube by setting a labyrinth structure to make the head produce rolling patterns to avoid opening, because the rear wall of the stainless steel tube is very thin and is easy to be extruded and cracked.

[0005] In addition, the length and width of the temperature sensor chip are only a few millimeters. After the wires led out from the temperature sensor chip are connected to the fiberglass wire, due to the certain bending of the positive and negative wires and the relatively short distance, when the product is vibrated or shaken, the two wires are easy to contact and are easy to short circuit under the energized state, resulting in burnout. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an automatic assembly device and an assembly method for a platinum sensor, which can basically automatically complete the assembly of the platinum sensor, improve the automation level, and meet the needs of customers.

[0007] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0008] An automatic assembly device for a platinum sensor, comprising a first turntable and a second turntable. Among them, a plurality of sets of sleeve baffle component jigs are circumferentially installed on the first turntable, and a two-way extrusion mechanism and a sealing and pressing mechanism are installed at appropriate positions on one side of the first turntable; a plurality of sets of electrical detection units are circumferentially installed on the second turntable, and a knocking mechanism is installed at an appropriate position on one side of the second turntable; a transfer and reaming mechanism is installed between the first turntable and the second turntable;

[0009] The two-way extrusion mechanism includes a front-back moving mechanism, an up-down extrusion mechanism and a left-right extrusion mechanism;

[0010] The front-back moving mechanism includes a first cylinder, and the first cylinder drives the mounting frame to move back and forth along the first slide rail. A first mounting seat is fixed at the front end of the mounting frame;

[0011] The up-down extrusion mechanism and the left-right extrusion mechanism have the same structure and are arranged perpendicular to each other. The up-down extrusion mechanism and the left-right extrusion mechanism both include a second slide rail. A first slider and a second slider are slidably arranged on the second slide rail. A pressing block is fixed on the opposite side of the first slider and the second slider. A first spring is arranged on the opposite side of the first slider and the second slider, and the first spring is connected to the second slide rail; a driving rod is arranged outside the first slider and the second slider. The rear end of the driving rod is connected to a second cylinder. The inner sides of the front ends of the driving rod are in contact with the first slider and the second slider, and the contact surface is an inclined surface. When the driving rods of the up-down extrusion mechanism and the left-right extrusion mechanism extend at the same time, the two pressing blocks of the up-down extrusion mechanism squeeze the sleeve up and down, and the two pressing blocks of the left-right extrusion mechanism squeeze the sleeve left and right;

[0012] The sealing and pressing mechanism includes a third slide rail. An upper slider and a lower slider are arranged on the third slide rail. A second spring is arranged between the upper slider and the lower slider. The outer sides of the upper slider and the lower slider are respectively in contact with a driving plate. The two driving plates are driven by a third cylinder; the contact surface between the driving plate and the upper slider and the lower slider is an inclined surface. When the driving plate moves forward, the driving plate drives the upper slider and the lower slider to approach each other relatively; first clamping plates are oppositely installed on the upper slider and the lower slider, and the two first clamping plates seal and flatten the sleeve;

[0013] The transfer and reaming mechanism includes a first manipulator, a second manipulator and a reaming mechanism;

[0014] The reaming mechanism includes a base, on which a first guide rail is horizontally arranged. A left slider and a right slider are slidably arranged on the first guide rail. On the opposite sides of the left slider and the right slider, there are grooves for clamping the sleeve. On the opposite sides of the left slider and the right slider, there are compression springs, and the other ends of the compression springs are fixed on the first guide rail. A lever is hinged left and right on the base. One end of the lever is driven to swing by a sixth cylinder, and the other end of the lever drives the left slider or the right slider to move. A seventh cylinder is arranged on the base opposite to the groove. The piston rod at the lower end of the seventh cylinder is connected to a reaming seat, and a reaming rod is installed at the lower end of the reaming seat.

[0015] On the opposite sides of the first slider and the second slider, traveling wheels are installed, and the traveling wheels are in contact with the inclined plane. On the sides of the upper slider and the lower slider in contact with the driving plate, rollers are installed. On the opposite sides of the left slider and the right slider, pulleys are installed, and the pulleys are in contact with the side surface of the lever.

[0016] The two pressing blocks of the up-and-down pressing mechanism are of square head structure, and the two pressing blocks of the left-and-right pressing mechanism are of pointed head structure.

[0017] At the corresponding positions of the two-way pressing mechanism and the sealing and pressing mechanism, first clamping mechanisms are installed. Each first clamping mechanism includes a lifting cylinder, which drives a clamping cylinder to move up and down. Second clamping plates are installed at the output ends on the left and right of the clamping cylinder, and the second clamping plates clamp the sleeve.

[0018] The second mounting seat is slidably arranged on the second slideway through a fourth slider, and the second mounting seat is driven to move back and forth by a fourth cylinder.

[0019] The first manipulator includes a fifth cylinder, which drives a first rotating cylinder to move up and down; the first rotating cylinder drives a second rotating cylinder to rotate horizontally, and the second rotating cylinder drives a first finger cylinder to rotate longitudinally; a third clamping plate matching the sleeve is installed at the output end of the first finger cylinder; the second manipulator includes a left-and-right moving cylinder, and a third mounting seat is installed at the output end of the left-and-right moving cylinder. Second clamping mechanisms are arranged at left and right intervals on the third mounting seat.

[0020] An automatic assembly method for a platinum sensor includes the following steps:

[0021] Step 1): The first turntable drives the sleeve retaining piece assembly on the sleeve retaining piece assembly fixture to intermittently move forward. When the sleeve retaining piece assembly reaches the two-way pressing mechanism, the first clamping mechanism clamps the sleeve; the two-way pressing mechanism performs left-right extrusion deformation and up-down extrusion deformation on the sleeve in the sleeve retaining piece assembly in the horizontal direction, and the deformation amounts in the left, right, up, and down directions are all between 2-3 mm;

[0022] Step 2), the first turntable drives the sleeve baffle assembly on the fixture of the sleeve baffle assembly to continue rotating. When the sleeve baffle assembly reaches the sealing and pressing mechanism, the first clamping mechanism clamps the sleeve; the sealing and pressing mechanism squeezes and deforms the sleeve in the vertical direction up and down in the sleeve baffle assembly, and the end of the sleeve is flattened and sealed to form a head.

[0023] Step 3), then the first turntable drives the sleeve baffle assembly on the fixture of the sleeve baffle assembly to continue rotating. When the sleeve baffle assembly reaches the intermediate reaming mechanism, the first manipulator clamps and lifts the sleeve baffle assembly on the first turntable. The first manipulator adjusts the sleeve baffle assembly from a horizontal state to a vertical state and changes the direction; then it is sent to the reaming mechanism by the second manipulator, and the reaming mechanism reams the end of the sleeve away from the head; after reaming is completed, the second manipulator sends the sleeve baffle assembly to the second turntable.

[0024] Step 4), manually place the temperature sensor assembly into the sleeve and insert the connector into the jack for intermediate wiring, thereby connecting the product into the test circuit; during the intermittent rotation of the product with the second turntable, the sleeve at the upper end of the product is squeezed from left and right, and the side wall of the sleeve is flattened and clamps the fiberglass wire; as it continues to rotate forward, the product is tested under the action of the knocking mechanism and without the knocking mechanism respectively to ensure that the product is powered on well regardless of whether there is vibration.

[0025] Step 5), after the detection is completed, the product can be taken off the second turntable by the manipulator.

[0026] An automatic assembly device and assembly method for a platinum sensor of the present invention have the following technical effects:

[0027] 1), by adopting a bi-directional extrusion mechanism mainly composed of a slide rail, an upper slider, a lower slider, a driving plate and a spring, this mechanism can complete flattening when the cylinder extends, and the distance of the clamping plate moving up and down can be controlled by controlling the angle of the inclined surface of the driving plate and the displacement of the driving plate moving back and forth, which is simple and efficient; by adopting a sealing and pressing mechanism, after the bi-directional extrusion mechanism flattens and deforms the sleeve, the end of the sleeve can be further extruded and deformed to form a multi-layer folded head, ensuring good sealing and preventing high-temperature steam from entering during later installation and use.

[0028] 2), by adopting the first clamping mechanism, although the fixture on the turntable can clamp the sleeve baffle assembly to a certain extent, since the sleeve is relatively long, the sleeve is not clamped tightly, and the extrusion deformation of the bi-directional extrusion mechanism is only a few millimeters. By setting the first clamping mechanism, it is ensured that the sleeve will not move during sealing, the sealing is accurate, and the later sealing performance is good.

[0029] 3) By using the first manipulator, the sleeve retaining piece assembly can be adjusted to a vertical state, which facilitates subsequent reaming, machining of the flat head, insertion of the temperature sensor assembly, and electrical detection. By setting the second manipulator, the sleeve retaining piece assembly can be transferred from the first manipulator to the reaming mechanism and then to another turntable, realizing automated operation. By adopting the second clamping mechanism, compared with the existing arrangement of one cylinder above and one cylinder below the clamping plate, in this device, the sixth cylinder can be arranged on the back of the base, and there can be two groups of sixth cylinders, back to back, extending or retracting simultaneously. This reduces the space occupied by the clamping device left and right, facilitating the installation and operation of other equipment. By reasonably setting the opening degree when the left slider and the right slider open, when the left slider and the right slider open, they can support the retaining piece. And the vertical end face of the base can position one end of the retaining piece, making the left and right grooves align with the sleeve, ensuring that when the left slider and the right slider close and clamp later, the sleeve is located in the groove. After reaming the sleeve using the transfer reaming mechanism, a tapered hole is formed at the end of the sleeve, facilitating the rapid manual insertion of the temperature sensor assembly into the sleeve.

[0030] 4) By adopting the knocking mechanism, the knocking of the knocking mechanism on the product sleeve can cause the internal components to vibrate, which is convenient for checking whether the wires of the sensor chip are short-circuited in the vibrating state, simple and efficient.

[0057] As shown in Figure 1 Figure [not shown], an automatic assembly device for a platinum sensor includes a first turntable 1 and a second turntable 2. Both the first turntable 1 and the second turntable 2 are driven to rotate intermittently by independent driving devices. Among them, a plurality of sets of sleeve baffle component jigs 3 are circumferentially installed on the first turntable 1. As shown in Figure 13 Figure [not shown], the sleeve baffle component jig 3 is horizontally provided with a sleeve limiting groove and vertically provided with a baffle clamping groove. The sleeve baffle component is placed in the corresponding groove and is conveyed by the intermittent rotation of the first turntable 1. At a suitable working position on one side of the first turntable 1, a two-way extrusion mechanism 4 and a sealing and pressing mechanism 5 are installed. The two-way extrusion mechanism 4 and the sealing and pressing mechanism 5 extrude and seal one end of the sleeve 10.2 extending out of the first turntable 1 to form a head 10.5. A transfer and reaming mechanism 8 is installed between the first turntable 1 and the second turntable 2. The transfer and reaming mechanism 8 completes reaming and sends the product 10 from the first turntable 1 to the second turntable 2. A plurality of sets of electrical detection units 6 are circumferentially installed on the second turntable 2. The electrical detection unit 6 is used to perform electrical detection on the installed products. An upper extrusion mechanism and a knocking mechanism 7 are installed at a suitable working position on one side of the second turntable 2; the structure of the upper extrusion mechanism is basically the same as that of the left and right extrusion mechanism 4-3, except that the two pressing blocks are square-headed pressing blocks, so that a flat head 10.6 can be formed. The knocking mechanism 7 generates vibration by knocking the product. During the vibration process, if the two wires of the sensor are in contact short circuit, the product is unqualified and needs to be removed.

[0058] As shown in Figures 3 - 4 Figure [not shown], the two-way extrusion mechanism 4 includes a front and back moving mechanism 4-1, an up and down extrusion mechanism 4-2 and a left and right extrusion mechanism 4-3; among them, the front and back moving mechanism 4-1 is used to push the up and down extrusion mechanism 4-2 and the left and right extrusion mechanism 4-3 to extend forward or reset backward. The up and down extrusion mechanism 4-2 and the left and right extrusion mechanism 4-3 are arranged perpendicular to each other. After the up and down extrusion mechanism 4-2 and the left and right extrusion mechanism 4-3 extend forward, the end of the sleeve 10.2 is located between the four pressing blocks 4-2-4 of the up and down extrusion mechanism 4-2 and the left and right extrusion mechanism 4-3. When the four pressing blocks 4-2-4 extend simultaneously, the initial extrusion deformation of the sleeve sealing can be completed, that is, the sleeve 10.2 extends inward about 2-3 mm left and right, and the sleeve 10.2 is extruded about 2-3 mm up and down. After the up and down extrusion mechanism 4-2 and the left and right extrusion mechanism 4-3 reset backward, the first turntable 1 continues to rotate one station, and the next set of sleeve baffle components is conveyed to the two-way extrusion mechanism 4.

[0059] Specifically, as shown in Figures 5 - 6As shown in the figure, the front-back moving mechanism 4-1 includes a first cylinder 4-1-1, and the first cylinder 4-1-1 drives the mounting frame 4-1-2 to move back and forth along the first slide rail 4-1-3. The mounting frame 4-1-2 is composed of a bottom plate, left and right side plates and a plurality of transverse connecting plates. The mounting frame 4-1-2 is mainly used to fix the second cylinder 4-2-7 of the up-down extrusion mechanism 4-2 and the left-right extrusion mechanism 4-3. A first mounting seat 4-1-4 is fixed at the front end of the mounting frame 4-1-2, and the first mounting seat 4-1-4 is mainly used to fix the second slide rail 4-2-1 of the up-down extrusion mechanism 4-2 and the left-right extrusion mechanism 4-3.

[0060] As Figures 7 - 8 shown in the figure, the up-down extrusion mechanism 4-2 and the left-right extrusion mechanism 4-3 have substantially the same structure. The up-down extrusion mechanism 4-2 is vertically arranged, and the left-right extrusion mechanism 4-3 is horizontally arranged.

[0061] As Figures 7 - 8 shown in the figure, both the up-down extrusion mechanism 4-2 and the left-right extrusion mechanism 4-3 include a second slide rail 4-2-1, and the second slide rail 4-2-1 is fixed on the front end face of the first mounting seat 4-1-4. A first slider 4-2-2 and a second slider 4-2-3 are slidably arranged on the second slide rail 4-2-1. A pressing block 4-2-4 is installed at the upper ends of the first slider 4-2-2 and the second slider 4-2-3 through bolts, and the two pressing blocks 4-2-4 are arranged opposite to each other at intervals. A first spring 4-2-5 is provided on the opposite sides of the first slider 4-2-2 and the second slider 4-2-3, and the first spring 4-2-5 is connected to the connecting plate on the second slide rail 4-2-1. A driving rod 4-2-6 is provided outside the first slider 4-2-2 and the second slider 4-2-3. The driving rod 4-2-6 is U-shaped, and the rear end of the driving rod 4-2-6 is connected to the second cylinder 4-2-7, and the second cylinder 4-2-7 is fixed on the mounting frame 4-1-2.

[0062] As Figures 7 - 8As shown, the inner sides at the front end of the driving rod 4-2-6 are in contact with the first slider 4-2-2 and the second slider 4-2-3, and the contact surfaces are inclined surfaces 4-2-8. The front end of the inclined surface 4-2-8 inclines away from the sleeve 10.2. When the driving rods 4-2-6 of the up-and-down squeezing mechanism 4-2 and the left-and-right squeezing mechanism 4-3 extend simultaneously, the driving rod 4-2-6 squeezes the first slider 4-2-2 and the second slider 4-2-3, causing the first slider 4-2-2 and the second slider 4-2-3 to move closer to the sleeve 10.2. In this way, the two pressing blocks 4-2-4 of the up-and-down squeezing mechanism 4-2 squeeze the sleeve 10.2 vertically, and the two pressing blocks 4-2-4 of the left-and-right squeezing mechanism 4-3 squeeze the sleeve 10.2 horizontally. When the driving rods 4-2-6 of the up-and-down squeezing mechanism 4-2 and the left-and-right squeezing mechanism 4-3 retract simultaneously, the first slider 4-2-2 and the second slider 4-2-3 reset under the action of the first spring 4-2-5. Here, since the driving rods 4-2-6 of the up-and-down squeezing mechanism 4-2 and the left-and-right squeezing mechanism 4-3 are controlled by independent second cylinders 4-2-7, the actions of the up-and-down squeezing mechanism 4-2 and the left-and-right squeezing mechanism 4-3 do not need to be completed simultaneously. According to the actual squeezing effect, the action of one set of mechanisms can be adjusted to lag or lead the other set of mechanisms by a few seconds.

[0063] As Figures 7 - 8 shown, the walking wheels 4-2-9 are installed on the opposite sides of the first slider 4-2-2 and the second slider 4-2-3, and the walking wheels 4-2-9 are in contact with the inclined surface 4-2-8. This can reduce friction and make the movement of the walking wheels 4-2-9 and the driving rod 4-2-6 smooth.

[0064] As Figures 7 - 8 shown, the two pressing blocks 4-2-4 of the up-and-down squeezing mechanism 4-2 are of square head structure, and the two pressing blocks 4-2-4 of the left-and-right squeezing mechanism 4-3 are of pointed head structure. The two left-and-right pressing blocks 4-2-4 fold and push the two ends of the sleeve 10.2, and the two up-and-down pressing blocks 4-2-4 flatten the upper and lower end faces of the sleeve 10.2 for the first time, and the second flattening is carried out at the working station of the sealing and pressing mechanism 5.

[0065] Working principle and process of the double-sided extrusion mechanism 4: When the sleeve retaining plate assembly fixture 3 on the first turntable 1 rotates to this device and stops, at this time, the lifting cylinder 9-1 in the first clamping mechanism 9 rises, and then the left and right second clamping plates 9-3 of the clamping cylinder 9-2 contract, and the left and right second clamping plates 9-3 clamp the sleeve 10.2 on the sleeve retaining plate assembly fixture 3. Subsequently, the front and rear moving mechanism 4-1 drives the up and down extrusion mechanism 4-2 and the left and right extrusion mechanisms 4-3 to extend simultaneously, so that the end of the sleeve 10.2 is located at the center position of the four pressing blocks 4-2-4. The piston rods of the two second cylinders 4-2-7 both extend a certain length, and the four pressing blocks 4-2-4 extend from above and below, left and right simultaneously, to extrude and deform the end of the sleeve 10.2. Subsequently, the piston rods of the two second cylinders 4-2-7 retract, and the four pressing blocks 4-2-4 reset under the action of the first spring 4-2-5. Then, the front and rear moving mechanism 4-1 drives the up and down extrusion mechanism 4-2 and the left and right extrusion mechanisms 4-3 to retract and reset. The first turntable 1 continues to rotate a certain angle. When the next sleeve retaining plate assembly fixture 3 rotates to this device and stops, the extrusion and deformation of the next sleeve 10.2 continues.

[0066] As Figures 11 - 12 shown, the sealing and pressing mechanism 5 includes a third slide rail 5-1, which is vertically arranged. An upper slider 5-2 and a lower slider 5-3 are arranged on the third slide rail 5-1. The upper slider 5-2 and the lower slider 5-3 can both slide up and down along the third slide rail 5-1. On one side of the upper slider 5-2 and the lower slider 5-3, there are welded perforated ear plates, and the guide rod passes through the upper and lower perforated ear plates. A second spring 5-4 is sleeved on the guide rod between the upper and lower perforated ear plates. The second spring 5-4 is in a compressed state under normal conditions and can press the upper slider 5-2 and the lower slider 5-3 tightly against the driving plate 5-5 outside the upper slider 5-2 and the lower slider 5-3. The contact surface between the driving plate 5-5 and the upper slider 5-2 and the lower slider 5-3 is an inclined surface. When the driving plate 5-5 moves forward, the driving plate 5-5 drives the upper slider 5-2 and the lower slider 5-3 to approach relatively; when the driving plate 5-5 moves backward, due to the elastic force of the second spring 5-4, the upper slider 5-2 and the lower slider 5-3 move away relatively. The upper and lower driving plates 5-5 are connected by a connecting plate 5-9. The back of the connecting plate 5-9 is slidably arranged on the first slideway 5-11 through a third slider 5-10, and the first slideway 5-11 is fixed on the second mounting seat 5-12. The connecting plate 5-9 is driven to move back and forth by a third cylinder 5-6, and the third cylinder 5-6 is fixed on the second mounting seat 5-12.

[0067] As Figures 11 - 12As shown, when the third cylinder 5-6 extends, the drive plate 5-5 moves forward, and the drive plate 5-5 presses against the upper slider 5-2 and the lower slider 5-3. The upper slider 5-2 and the lower slider 5-3 move closer to each other, so that the two clamping plates 5-7 move closer to each other to complete the clamping; when the third cylinder 5-6 retracts, the drive plate 5-5 moves backward accordingly, and the second spring 5-4 pushes the upper slider 5-2 and the lower slider 5-3 outwards. The upper slider 5-2 and the lower slider 5-3 move away from each other, and the two clamping plates 5-7 separate.

[0068] As Figures 11 - 12 shown, in addition, the second mounting seat 5-12 is slidably arranged on the second slideway 5-14 through the fourth slider 5-13, and the second mounting seat 5-12 is driven to move back and forth by the fourth cylinder 5-15. As Figure 1 shown, during the rotation of the turntable, the secondary extrusion mechanism 2 is located on one side of the sleeve 10.2. By extending the fourth cylinder 5-15, the sleeve 10.2 is located between the two clamping plates 5-7, which facilitates the clamping and flattening of the two clamping plates 5-7.

[0069] As Figures 11 - 12 shown, preferably, rollers 5-8 are installed on the sides of the upper slider 5-2 and the lower slider 5-3 that contact the drive plate 5-5. This can reduce friction and make the movement of the drive plate 5-5 and the upper slider 5-2 or the lower slider 5-3 smooth.

[0070] As Figure 13 shown, the transfer and reaming mechanism 8 includes a first manipulator 8.1, a second manipulator 8.2 and a reaming mechanism 8.3; the first manipulator 8.1 is used to lift the sleeve retaining plate assembly on the first turntable 1, then turn it over and adjust it to the vertical state, and then adjust the direction; the second manipulator 8.2 is used to transfer the sleeve retaining plate assembly at the first manipulator 8.1 to the reaming mechanism 8.3, and after reaming, transfer it to the second turntable 2 for subsequent processing.

[0071] As Figure 14As shown, the first manipulator 8.1 includes a fifth cylinder 8.1.1 which is vertically arranged. The output end of the fifth cylinder 8.1.1 is connected to a first connecting plate. A first rotary cylinder 8.1.2 is installed on the first connecting plate. The fifth cylinder 8.1.1 can drive the first rotary cylinder 8.1.2 to move up and down. The first rotary cylinder 8.1.2 is vertically arranged. The output end at the upper end of the first rotary cylinder 8.1.2 is installed with a second rotary cylinder 8.1.3. The first rotary cylinder 8.1.2 drives the second rotary cylinder 8.1.3 to rotate circumferentially in the horizontal plane. The second rotary cylinder 8.1.3 is horizontally arranged. The output end of the second rotary cylinder 8.1.3 is installed with a first finger cylinder 8.1.4. The second rotary cylinder 8.1.3 drives the first finger cylinder 8.1.4 to rotate in the longitudinal plane. The output ends of the first finger cylinders 8.1.4 are installed with third clamping plates 8.1.5 that match the sleeves 10.2. The two third clamping plates 8.1.5 can clamp the sleeves 10.2.

[0072] As Figure 19 , Figure 13 shown, when the sleeve baffle assembly is clamped and lifted, the second rotary cylinder 8.1.3 connected to the first finger cylinder 8.1.4 rotates counterclockwise 90 degrees in the longitudinal plane, making the sleeve baffle assembly change from horizontal to vertical with the baffle facing up. Then the first rotary cylinder 8.1.2 rotates clockwise 90 degrees in the horizontal plane, thus forming Figure 13 the state shown. This facilitates the clamping by the second manipulator 8.2. After the second manipulator 8.2 clamps, the first finger cylinder 8.1.4 releases. Then the first rotary cylinder 8.1.2 and the second rotary cylinder 8.1.3 rotate in the reverse direction to reset. The fifth cylinder 8.1.1 descends. The third clamping plate 8.1.5 of the first finger cylinder 8.1.4 is aligned with the sleeve of the next set of sleeve baffle assemblies rotated to this station. The first finger cylinder 8.1.4 acts again to clamp the sleeve of the sleeve baffle assembly. The fifth cylinder 8.1.1 ascends, forming Figure 19 the state shown. Continue the above process to complete the orientation adjustment of the sleeve baffle assembly.

[0073] As Figure 15 shown, the second manipulator 8.2 includes a left - right moving cylinder 8.2.1 which is a rodless cylinder. The output end of the left - right moving cylinder 8.2.1 is installed with a third mounting seat 8.2.2. The left - right moving cylinder 8.2.1 drives the third mounting seat 8.2.2 to move left and right. Second clamping mechanisms 8.2.3 are arranged at intervals left and right on the third mounting seat 8.2.2. The second clamping mechanism 8.2.3 on the right is mainly used to transfer the sleeve baffle assembly at the first manipulator 8.1 to the reaming mechanism 8.3. The second clamping mechanism 8.2.3 on the left is mainly used to transfer the sleeve baffle assembly at the reaming mechanism 8.3 to the second turntable 2.

[0074] As Figure 15 shown, among which, the second clamping mechanism 8.2.3 on the right side includes a front-back air cylinder 8.2.4, and the front-back air cylinder 8.2.4 is fixed on the third mounting seat 8.2.2. The front-back air cylinder 8.2.4 is also a rodless air cylinder, and a second finger air cylinder 8.2.5 is installed at the output end of the front-back air cylinder 8.2.4, and a fourth clamping plate 8.2.6 matching the sleeve 10.2 is installed at the output end of the second finger air cylinder 8.2.5.

[0075] As Figure 15 shown, the second clamping mechanism 8.2.3 on the left side is basically the same as the second clamping mechanism 8.2.3 on the right side. The only difference is that the front-back air cylinder 8.2.4 is fixed on a vertically arranged up-down lifting air cylinder, and the up-down lifting air cylinder is fixed on the third mounting seat 8.2.2.

[0076] After the sleeve retaining plate assembly at the first manipulator 8.1 is conveyed and positioned, the front-back air cylinder 8.2.4 on the right side drives the second finger air cylinder 8.2.5 on the right side to extend forward. The second finger air cylinder 8.2.5 clamps the sleeve retaining plate assembly at the first manipulator 8.1, and then the front-back air cylinder 8.2.4 on the right side drives the second finger air cylinder 8.2.5 to retract. At the same time, the front-back air cylinder 8.2.4 on the left side drives the second finger air cylinder 8.2.5 on the left side to extend forward. The second finger air cylinder 8.2.5 on the left side clamps the sleeve retaining plate assembly at the reaming mechanism 8.3, and then the front-back air cylinder 8.2.4 on the left side drives the second finger air cylinder 8.2.5 to retract. Subsequently, the left-right moving air cylinder 8.2.1 drives the two groups of second clamping mechanisms 8.2.3 on the third mounting seat 8.2.2 to move leftward by a certain distance. One group of second clamping mechanisms 8.2.3 on the right side is aligned with the reaming mechanism 8.3, and one group of second clamping mechanisms 8.2.3 on the left side is aligned with the second turntable 2. The front-back air cylinder 8.2.4 in one group of second clamping mechanisms 8.2.3 on the right side extends, and the second finger air cylinder 8.2.5 releases, and the sleeve retaining plate assembly to be reamed is placed at the reaming mechanism 8.3. The front-back air cylinder 8.2.4 in one group of second clamping mechanisms 8.2.3 on the left side extends. After the up-down lifting air cylinder descends, the second finger air cylinder 8.2.5 releases, and the sleeve retaining plate assembly that has been reamed is placed on the fixture of the second turntable 2.

[0077] As Figures 16 - 17As shown, the reaming mechanism 8.3 includes a base 8.3.1. The base 8.3.1 is T-shaped and consists of a vertical plate and a horizontal plate. The base 8.3.1 is fixed on the platform 11. A first guide rail 8.3.2 is transversely provided at the lower part of the base 8.3.1. A left slider 8.3.3 and a right slider 8.3.4 are slidably arranged on the first guide rail 8.3.2. A groove 8.3.5 for clamping the sleeve 10.2 is provided on the opposite side of the left slider 8.3.3 and the right slider 8.3.4. The cross-section of the groove 8.3.5 is semi-circular, and the diameter matches that of the sleeve 10.2. Compression springs 8.3.6 are provided on the opposite sides of the left slider 8.3.3 and the right slider 8.3.4, and the other ends of the compression springs 8.3.6 are fixed on the connecting plate of the first guide rail 8.3.2. A lever 8.3.7 is hinged left and right on the base 8.3.1, and the lever 8.3.7 is driven to swing by a sixth cylinder 8.3.8. A seventh cylinder 8.3.9 is vertically installed above the center between the two grooves 8.3.5 on the base 8.3.1. The piston rod at the lower end of the seventh cylinder 8.3.9 is connected to a reaming seat 8.3.10, and a reaming rod 8.3.11 is installed at the lower end of the reaming seat 8.3.10. The reaming rod 8.3.11 can ream the sleeve 10.2.

[0078] As Figure 17 shown, the back surface of the reaming seat 8.3.10 is slidably arranged on the second guide rail 8.3.12 through a slider. This ensures that the reaming rod 8.3.11 moves vertically up and down.

[0079] As Figure 17 shown, pulleys 8.3.13 are installed on the opposite sides of the left slider 8.3.3 and the right slider 8.3.4, and the pulleys 8.3.13 are in contact with the side surface of the lever 8.3.7. This can reduce friction and ensure smooth and unobstructed movement.

[0080] As Figure 17 shown, the reaming rod 8.3.11 is conical with a thin lower end and a thick upper end. This enlarges the upper end of the sleeve 10.2 a little, making the port of the sleeve 10.2 flared and facilitating the insertion of the temperature sensor assembly.

[0081] During operation, when the second manipulator 8.2 in the front clamps and places the casing baffle assembly between the left slider 8.3.3 and the right slider 8.3.4, the rear end of the baffle 10.3 is positioned by the front end face of the vertical plate of the base 8.3.1, so that the casing 10.2 is opposite to the groove 8.3.5. Then the sixth cylinder 8.3.8 extends outwards, and the front end of the lever 8.3.7 approaches the side of the casing 10.2. In this way, the two levers 8.3.7 will squeeze the left slider 8.3.3 and the right slider 8.3.4, causing the left slider 8.3.3 and the right slider 8.3.4 to approach the casing 10.2 and finally clamp the casing 10.2. At this time, the compression spring 8.3.6 is in a stretched state. Subsequently, the seventh cylinder 8.3.9 extends, and the reaming rod 8.3.11 reams the casing 10.2; after the reaming rod 8.3.11 retracts, the sixth cylinder 8.3.8 contracts, and the left slider 8.3.3 and the right slider 8.3.4 reset under the elastic force of the compression spring 8.3.6. The left slider 8.3.3 and the right slider 8.3.4 release the casing 10.2, and only the baffle 10.3 is placed on the end faces of the left slider 8.3.3 and the right slider 8.3.4, and then it is transferred to the second turntable 2 by the second manipulator 8.2.

[0082] As Figure 20 shown, the electric detection unit 6 is circumferentially installed on the second turntable 2 in multiple groups. The multiple groups of electric detection units 6 are evenly and equidistantly arranged, and the electric detection unit 6 can be powered on to detect whether the circuit of the product is qualified. A knocking mechanism 7 is installed on the platform 11 outside one group of the electric detection units 6. The knocking mechanism 7 is used to vibrate the components inside the casing. During the vibration, if the two wires of the sensor come into contact short circuit, then the product is unqualified and needs to be removed.

[0083] As Figures 21 - 22 shown, the electric detection unit 6 includes a product positioning fixture 6-1, a transfer connection fixture 6-2 and a wiring terminal 6-3; among them, the product positioning fixture 6-1 is used to vertically place and position the product 10. The transfer connection fixture 6-2 is used to fix the plug at one end of the transfer wiring 6-4. And the wiring terminal 6-3 is used for the electrical connection of the transfer wiring 6-4 and the main wiring 6-5, and the main wiring 6-5 is connected into the detection circuit.

[0084] As Figures 21 - 22As shown, specifically, the product positioning fixture 6-1 includes a positioning base 6-1-1. A through hole 6-1-2 is vertically drilled on the positioning base 6-1-1. The diameter of the through hole 6-1-2 is larger than the diameter of the sleeve 10.2 of the product 10, facilitating the insertion of the sleeve 10.2 of the product 10. It can be inserted by a manipulator or manually. One side of the upper end of the positioning base 6-1-1 is provided with a positioning post 6-1-3. After the retaining piece 10.3 of the product 10 is placed on the upper end surface of the positioning base 6-1-1, the positioning post 6-1-3 is inserted into the mounting hole of the retaining piece 10.3, so as to keep the direction of the product roughly consistent.

[0085] Manually insert the connector 10.1 of the product 10 into the plug of the transfer wiring 6-4. The transfer wiring 6-4 is connected to the detection circuit through the main wiring 6-5. Detection can be completed after power-on.

[0086] As Figures 21 - 22 shown, the transfer connection fixture 6-2 includes an L-shaped base 6-2-1. Two groups of screw rods 6-2-2 are horizontally arranged on the vertical plate at the rear end of the L-shaped base 6-2-1. The pressing plate 6-2-3 passes through the screw rods 6-2-2 and is locked by nuts. The lower end of the pressing plate 6-2-3 is spaced from the bottom surface of the L-shaped base 6-2-1, facilitating the passing of the transfer wiring 6-4. Adjust the gap between the pressing plate 6-2-3 and the middle of the vertical plate of the L-shaped base 6-2-1 according to the size of the plug of the transfer wiring 6-4, and the plug of the transfer wiring 6-4 can be tightened. By setting the transfer connection fixture 6-2, the transfer wiring 6-4 can be made detachable, so that it can be conveniently replaced according to different products produced.

[0087] As Figure 4 shown, the knocking mechanism 7 includes multiple groups of eighth cylinders 7-1. A striking block 7-2 is fixed to the extending end of each group of eighth cylinders 7-1. The multiple groups of striking blocks 7-2 are intermittently arranged in a column from top to bottom. The striking block 7-2 is made of rubber, and the rubber has a certain flexibility to avoid knocking the sleeve 10.2 out of shape. The striking block 7-2 is opposite to the sleeve 10.2 of the product 10. A limiting plate 7-3 is fixed on the platform 11 on the back of the sleeve 10.2. The limiting plate 7-3 has a small gap with the sleeve 10.2. The limiting plate 7-3 can provide vertical limiting support when the striking block 7-2 knocks the sleeve 10.2. When a group of electric detection units 6 reaches the knocking mechanism 7, the second turntable 2 stops moving. The multiple groups of eighth cylinders 7-1 complete the knocking of the sleeve 10.2 through rapid multiple expansions and contractions. At the same time, power-on detection is carried out to check whether the product is qualified and whether there is a short circuit.
